I don't see much difference with Hinkley Point C started 10 years after Flamanville 3. Timelines and costs are about equal.

...as opposed to wind, solar, biofuel, tidal and other similar technologies failing at large scale projects?

Large-scale solar is less susceptible to these budget problems as the technology is more mature. The problems here mostly centre around power distribution and the unpredictable nature of (PV) solar power where production can go from close to zero to maximum in the span of a few seconds only to drop down to close to zero again after a few more seconds. Roof-top solar has become so popular that the distribution networks are getting overloaded on sunny days. In e.g. the Netherlands those who have roof-top solar power installations are starting to get billed for delivering power back to the network [1,2]. These problems can be solved by installing local energy storage - 'home batteries' - but these are as it stands too expensive to be economically feasible.
I live in Sweden and have a 14.5 kW solar installation on a barn roof. When I installed this I signed a 5-year contract which enables us to sell power back to the network at market rates. I do not expect us to be able to sign a similar contract once this one runs out and will have to consider adding energy storage to the system - this is why I installed a hybrid inverter when I built the system.

Since the projects are so predictable the developers called it quits. In a perfect world they would have hedged their costs but here we are.
Have a look at Bent Flyvbjergs work. Nuclear power is only beaten by the Olympics and nuclear waste storage in risk of cost and schedule escalations. Solar and wind occupy the other end of the spectrum.
A hunch would say that the first large scale off shore wind projects in the US falls in the middle of the spectrum, but nowhere near nuclear power. As evidenced by the developers having such good grasp of the costs that they canceled the projects the instant they stopped being viable instead of continuing down a path of sunk cost fallacies.
